Our solution involved following our innovative top-down approach, where we developed our system within a predefined road route scenario. Additionally, the operational design domain of the system was defined. The various functions were developed as a system, with safety analyses and item definitions created for the entire system. Furthermore, use case diagrams, as well as functional, logical, and physical architectures and requirements for each function, were developed. The functional safety concept and technical safety concept were created, with regular alignment meetings held with cybersecurity. In the end, a functional architecture of the ECU was developed to integrate all functions and ensure traceability to each function.
